` snow and ice from pavements and roadways and is in the form of a hand truck employing a fuel tank having a pump vdevice associated therewith and burners positioned adjacent the ground for purposes of directing a flame jet directly on the gathered ice or snow. Y

With the above and other objects in view, the invention consists inthe novel form,

combination and arrangement of parts herel in fully described and shown in the Vaccompanying drawings wherein like reference characters indicate similar parts throughout the several views.

In the drawing,

Figure 1 is a vertical sectional view of a street cleaner constructed in accordance with the present invention, a fuel tank being shown in section, and

Fig. 2 is a top plan view of the burner set detached from the remaining mechanism.

Referring more in detail to the accompanying drawing, there is illustrated a hand truck embodying supporting wheels 3 journaled upon an aXle 4 which in turn supports a platform 5 for carrying all of the parts of the device, a handle 6 being carried by the platform 5 and provided withfa grip 7 for purposes of moving the truckvover a pavement.

A tank 8 having a filling spout 9 at its upper end closed by a screw cap 10 is adapted to contain a quantity of fuel such as gasolene or kerosene as indicated by the dotted line contents. The rear end of the platform 5 adjacent the handle 6 carries a hand operated pump 11 havin a pipe connection 12 with the interior o said tank as'at 14 and is supported in a bearing 13 exteriorly of the tank 8. A11 end valve 15 is provided in the upper end of the pipe 12 for purposes of retaining the air in the tank that of the` tank 8 to indicate the gas volume-in the tank. l i

A burner set is carried by the forward side of the tank 8 and includes a pair of brackets 17 in which is secured a pipe 18 having an .extension 19 within the tank, the lower end of the pipe 19 opening adjacent the lower end of the tank and below the level of theffuel therein, a hand valve 2O being provided in the pipe 18 for purposes of Y controlling theflow of fuel issuing through the pipe 19. vA forward lrest or foot 21 carries an upstanding support 22 for the extension 23 of the pipe 18 whereby the truck is supported in an upright position as indicated with the foot 21 resting upon the pavement A. The forward projection 23 of the pipe 18 is mounted in the upper end of the support v22 and projects fon wardly thereofv as indicated in Fig. 1 and is provided with a lateral branch pipe 24 angularly extending therefrom at opposite sides, and to which branch is connected a plurality of S-shaped connectors 25 having the free ends thereof directed into the rear ends of vthe conically-shaped burners 26 which are provided with a plurality of air openings 27 for purposes of aiding combustion. As shown in Fig. 2, the branch pipe 24 is connected as at 28 to the forward eX- tension 23 of the fuel supply pipe 18 and is rotatable in the connection 28 whereby the angularity of the burners 26' supported on the Sshaped members 25 may be regulated, this change in position being obtained by the provision of a bracket 29 upon the pipe 23 and having pivoted in the upper end thereof, a bell crank 30, one end of which has a link connection 31 with one of the burner members 25 while the other end of the bell crank has a long arm 32 connected thereto, with the handle portion 33 thereof extending in proximity of the handle 7 and provided with a rack 34 engageable with an adjacent part of the handle.

From the above detailed description of the invention, it is thought that the construction and operation thereof will at once be apparent, it being noted that the fuel contents of the container 8 are forced therefrom by the air within the upper end of the container into the outlet pipe 19 of the supply pipe 18, the air being supplied to the tank through the medium ofthe pump 11,

by the gage 16 `while the petcock l5 prevents: the back escape of air from the tank. VThe rectly forward of the truck, While the device p is readily transportable during operation by slightlyv elevating the foot 2l from the ground line A to permit a rolling movement of the supporting Wheels 3..

Vhile there is herein shown and described What is believed to be the preferred embodiment vof the invention, it is nevertheless to be understood that minor changes may be made in the form, combination and arrange ment of parts Without departing from the spirit and scope of the invention as claimed.

What is claimed as new is l. A burner for street cleaners including distributingpipes reversely at their opposite ends and having kone end connected to thel branch pipe with the intermediate nozzles supported on the distributing pipes forwardly of the free ends thereof. 'f

2. A burner for street cleaners including a supply' pipe, Va branch pipe Y extending transversely of the outer end thereof and rotatably supported by said supply pipe, distributing pipes reversely curvedat their opposite ends and having one end connected to the branch pipe With the intermediate portion overlying the branchV pipe,-jetv noz` zles supported on the distributing pipes or- C;

Wardly of the free ends thereof, and means engaging one lof said distributing pipes for partially rotating the transverse pipe to varyk the inclination` of the jet nozzles.
